Abstract

When the semi-automatic sealing device for the ship-shaped hopper is used, after the ship-shaped hopper is filled with materials, the elastic force of the elastic rope is overcome to pull the left movable rod leftwards until the left movable rod is adjacent to the left ends of the front and rear sliding rails, so that the flexible sealing sheet body is unfolded to cover the upper opening of the ship-shaped hopper, and the hook movably connected with the left movable rod falls down; the method comprises the following steps: hooking a left end bow part of a ship-shaped hopper, fixing a left movable rod, ensuring that a flexible sealing sheet body stably covers an upper opening of the ship-shaped hopper, hoisting the ship-shaped hopper to a specified position, lifting a hook, separating the hook from the left end bow part of the ship-shaped hopper, shrinking and shortening an elastic rope, driving the left movable rod to move rightwards, and folding the flexible sealing sheet body. Therefore, the upper opening of the ship-shaped hopper is opened, and the materials in the hopper can be transferred to a designated position. The ship-shaped hopper can be sealed, materials are prevented from being overloaded, and the loaded materials are effectively prevented from falling off and throwing off, so that the hoisting safety is ensured.
